LOOM

Filed June 5, 1935' 5 Sheets-She et s v Patented v Oct. 20, 1936 UNITEDSTATES This invention relates to looms, and has for one of its principalobjects the production of a simple loom structure which may be foldedinto acompact space thereby facilitating transportaa tion of the loomfrom'house to house, or place to place.

Another object of this invention is the provision of a simple means bywhich the loom may be .collapsed and later set-up at a place ofoperation in without necessitating a great amount of skill.

A still further object of this invention is the production of a simpleand efficient folding loom wherein the warp may be put in and Weavestarted before the loom is folded for shipment.

1 Other objects and advantages will appear throughout the followingclaims. a

In the drawings:

Figure Us a side elevation of the loom in a setup position;

Figure 2 is 'a top plan view, certain parts being broken' away and shownin section;

Figure 3 is a top plan view of the loom, certain parts being removedprior to folding;

.Figure 4 is a top plan view of the loom in its folded position;

Figure 5 is a section taken on line 55 of Figure 4 showing the loom inits folded position;

Figure 6 is a section taken on line 66 of Figure 5;

Figure '7 is a front elevation of the loom in a set-up position;

Figure 8 is a rear elevation of the loom in a set-up position;

35 Figure 9 is a front elevation of the loom in a folded position;

Figure 10 is a rear elevation of the loom in a folded position.

By referring to the drawings, it will be seen that '15 designates themain frame which consists of a pair of side sections l6 which aresimilarly constructed. These side sections it are adapted to extend in avertical position and support the conventional loom mechanism embodyinga warp beam or bar ll and a cloth beam l3 which may be pushed back as isshown in Figure 1, when the loom frame is folded.

It should be borne in mind that the present invention relates to thestructure of a folding loom frame and any suitable or desired loommechanism may be associated therewith Without departing from the spiritof the invention.

The main frame l5 carries a front folding frame consisting of foldingside members I9 which are vertically hinged as at to the frontspecification and edge of the main frame l5.Note particularly Figure 3.Each front side frame [9 is provided with a forward upright 2| having adove-tail socket 22 formed at its upper extremity, and a transverselyextending breast beam 23 spans the distance between the forward sideframes IQ for holding these side frames in set-up extended position,such as is shown in Figure 2. This breast beam 23 is provided withdove-tail tongues 24 which releasably fit within the sockets 22 therebypermitting the breast beam to be easily removed from engagement with thefront or forward side frames l9 prior to being folded. The front orforward side frames i?! are provided with forwardly extending bottomrails 25, which bottom rails 25 are provided with extending ends 26projecting beyond the forward uprights 21. A detachable treadle bar 21rests upon the forward ends 26 and this treadle bar is detachably heldin engagement with the forward extensions 26 throughthe medium of aninterfitting pin conis in this Way removable from the forward or,

front side sections l9, thereby permitting the side sections l9 to befolded in the direction of the arrows shown in Figure 3.

A rear folding frame 30 is vertically hinged to the main frame andconsists of a pair of similarly constructed side sections 3|, which sidesections are hinged to the main frame l5 by the vertically extendinghinges 32. Each rear side frame 3! is provided with a rear upright 33having an upwardly extending end portion 34 which is notched, as at 35,upon its rear face for receiving the warp bar 36, the ends of which arenotched, as at 37, and fit into the sockets 35 Pins 38 are carried bythe respective ends of the warp bar 36 for detachably fitting intosuitable sockets formed in the uprights 33, as will be obvious byconsidering the drawings.

From the foregoing description it will be seen that a very simplefolding loom frame has been provided, certain parts of which may bereadily detached for the purpose of permitting other parts to beconveniently folded and thereby allow the frame to be accommodated in aminimum amount of space. At the same time, it should be understood thatcertain portions of the frame may be extended and other parts assembledto provide an efiicient loom frame possessing the characteristics of theconventional loom and permitting the same functions to be performed. Itis not desired to limit the present application to any particular typeof loom mechanism.

When it is desired to use the loom, the main frame is set-up in avertical position, such as is shown in Figure 1, and the forward andrear frames l9 and 30 respectively are moved to an extended positionwhereby the side frames l9 and 3| may extend at right angles to thefront and rear faces of the main frame 15 and the treadle bar, breastbeam, and warp bar may then be placed in proper position as is shown inFigures 1 and 2. The loom will then be in its set-up position ready foroperation, and the treadles 29 may be connected in the conventionalmanner. Due to the type of structure illustrated it will be seen thatthe present loom frame is especially adapted for transportation from oneplace to another and may be used for demonstrating purposes as well asfor the purpose of giving instructions with respect to the operation ofthe loom and with respect to weaving.

Also because of the present structure and the fact that the mainoperating parts may be carried by the main frame I5, as illustrated,(note Figure 5), the warp may be placed in the loom and the weavestarted before the loom is folded and shipped.

When it is desired to fold the loom frame, the treadle bar 21, thebreast beam 23, and the warp bar 36 are released, and the end frames l9and 3| will fold inwardly toward the main frame l5, as indicated inFigure 3, and the treadles 29, the treadle bar, breast beam, and warpbar may be tied together or carried in any suitable or desired manner.When the loom frame is folded, it will require only about one-third ofthe space which is necessary when the loom is set-up.

By noting particularly Figure 1, it will be observed that the warp baror beam 36 is placed above or on top of the rear side frames 2|, therebyfacilitating the adjustment of the cords under the beam or bar. This isaccomplished by loosening the ratchet wheel and the bar that holds thewarp may be pulled out and placed on top of the loom while assembling orplacing the loom in a set-up position. The conventional beater may behung from the top or in any convenient or suitable manner.

It should be understood that certain detail changes in the mechanicalstructure, combination or arrangement of parts may be employed withoutdeparting from the spirit of the inven-,

tion, so long as such changes fall within the scope of the appendedclaims.

Having described the claimed as new is:
